• B

• C
  2% (1)
• D
  5% (3)

Explanation

There's a discrepancy worth flagging: based on standard data center classifications, the correct answer should be A (Server), not B.

Why A (Server) is not a network device: Servers are computing equipment - they process and run applications. The question itself frames the three categories as computing, storage, and network; servers belong to the first.

Why B, C, and D are network devices:

• Load balancing (B): A network appliance that distributes incoming traffic across multiple servers - it sits in the network path and makes routing decisions.
• Firewall (C): A core network security device that filters traffic between network zones.
• IDS/IPS (D): Intrusion Detection/Prevention Systems monitor and act on network traffic - definitionally network devices.

Memory tip: Think of the three data center pillars - Compute (servers), Storage (SANs, NAS), Network (everything that moves or controls traffic: switches, routers, firewalls, load balancers, IDS/IPS). Anything that sits in the traffic path = network device.

If your source material marks B as correct, it may be a typo or a translation artifact from Chinese exam materials - I'd verify against your official study guide, as A is the answer supported by standard definitions.
